Disinfectants are NOT __

• A. They are able to destroy all bacteria.
• B. They are not used in salons.
• C. They are NOT able to destroy all bacteria.
• D. They are safe on skin.

Answer: (C)

Disinfectants are designed to kill many microorganisms on inanimate surfaces, but they do not guarantee destroying every bacterium. Some bacteria, especially spores or highly resistant strains, can survive disinfectant exposure, and effectiveness depends on factors like the product’s concentration, contact time, cleanliness of the surface, and presence of organic matter. In salon settings, disinfectants are used to sanitize tools and surfaces, but they are not safe for skin contact and are not meant to sterilize every microorganism. Therefore, the statement that disinfectants are NOT able to destroy all bacteria is true—their purpose is to reduce and control microbes, not eliminate every single one.
